RSTP provides different functions in different scenarios. Which of the following statements is false?

The statement indicating that if the edge port on the switch is enabled with BPDU protection receives an RST BPDU, it sets the edge port as a non-edge port is indeed a misconception. In reality, BPDU protection is designed to prevent potential loops by disabling the port if it receives a BPDU. When an edge port configured with BPDU protection receives a BPDU, it does not simply change its designation to a non-edge port; instead, it gets put into an error-disabled state.

This functionality is crucial in preventing unintended participation in the RSTP topology, thereby ensuring stable network operation and the avoidance of loops that could disrupt communication paths. Understanding this mechanism is essential for configuring RSTP appropriately and knowing how edge ports are supposed to behave under specific scenarios.

The other statements hold true in the context of RSTP: the designated port's role remains unchanged under root protection, specific states in RSTP determine how ports respond to the receipt of BPDUs, and edge ports have the capacity to receive RSTP BPDUs depending on their configuration.
